After chasing the Medford job, I had a little time to hang out on the main line north of Spencer. Within a short amount of time, this southbound stack train came roaring through.
I wold love to acknoledge the person who stacked the coins and took the photo, however, I don't know who he or she is. So thank you to you. Love the shot.

Village near Salcombe, Devon. The street descends sharply, into a dip and then out again, revealing these "stacked" buildings with varying pastel colours. Shot with a telephoto to compress the perspective!
My panorama push of the last year has been my image focus as I get my image libraries into Lightroom 6/CC. Still a lot to do with the libraries and sorting, so it will be ongoing. I pretty much have only just started with how to process with Lightroom 6. Someday i will move on to photoshop CC. As you can see with the 'panorama's I've a lot to learn there as well. It has been fun and don't mind leaving some slightly flawed panoramas in to provide an enhanced perpective of this photographers view. This grouping here is a 'new learning curve' that I will briefly and occasionally provide some results from. These 13 images are the results of 119 images taken to learn "focus stacking" with Helicon Focus. Some fun and interesting results as was the first Tour Eiffel night image (stacked together two handheld vertical panoramas earlier in my photo stream). Did not expect any results from that attempt. These 13 images show promice even with the learning curve ahead of me. I mistakenly mixed my jpeg and RAW images into the stacks, so no wonder I had many difficulties & failures with little additional "focus" showing. Still, I am enjoying the results and especially liked some of the frost images. Hope some of you learn the ins and outs of the new processes like 'focus stacking' quicker than I and enjoy it as much. Thank you all for your time, favs and comments.

Navajo Loop Trail, Bryce Canyon National Park
Every sight at Bryce Canyon was uniquely beautiful. The layers of contrasting textures and colors in this one almost reminded us of some kind of exotic dessert. Well, the appetite of our eyes was satisfied for sure!
Stacked using Zerene Stacker trial edition. Initial impressions greatly exceed photoshop's capabilities when it comes to stacking.
Some browsers have automatic image sizing.
After clicking the link you may have to click on the photo to see the original size.
There are so many CDs in cardboard and digipak covers that I've had to lower the height of the stacks and add some support to create stable stacks.
Rubbermaid Stackable Recyclers make recycling easy! Three sizes can be stacked and interchanged to suit your sorting needs. The flip door makes unloading recyclables a breeze. Stickers allow you to label your bin so you can see if you are sorting glass, paper, plastic, etc. The hood snaps securely to the base so you can transport your recyclables to a facility if necessary.

STACKED PILLOW CAKES THAT I MADE FOR MY MOMMA'S 57th BIRTHDAY WHILE I WAS ON VACATION IN THE DOMINICAN REPUBLIC THIS SUMMER.
SHE SHOWED ME HOW TO MAKE THESE FLOWERS AND SHE HAD NOOOOOO CLUE I WAS MAKING THEM FOR HER OWN CAKE!!! HAHAHA! SHE WAS SURPRISED, SHE LOVED IT WE CRIED AND IT WAS A PARTY TO REMEMBER!
LOVE YOU MOM!

Some time ago I built a wooden flexure stage because I wanted to take focus-stacked macro photos. Originally the contraption was meant to be operated manually, but last week Sophia automated the thing as part of a homework project for her high school electronics class. An Arduino microcontroller drives a motor that advances the stage towards the camera in tiny steps, and a relay that triggers the camera. The size and the number of steps, and how much time the camera needs between steps to take a picture, are entered via an infrared remote control.
First use of "Focus Stacking" made available in version 4 Firmware for Olympus E-M1. 8 images are recorded at different focal lengths and the results merged in camera to produce a better focussed image. Simple and impressive given the poor light. Version 4 also includes "Focus Bracketing" which records up to 999 images but needs third-party software on your computer to produce a composite.
Dorytomus sp. I'm leaning towards D. tremulae
Size: 5 mm
Like many weevils, Dorytomus-species can fold their first (elongated) antennae-segments into slots at either side of the snout. If you look carefully at the high resolution version you might be able to tell that the antenna socket is located half way down the snout.
Stacked from 126 exposures in Zerene Stacker.
Mitutoyo M Plan Apo 10X 0.28 + "morfanon" tube lens
Driving to Freshwater West a while back I spotted the old house with all those stacks and noticed the way it sat against the backdrop of the stacks of one of the oil refineries on the south side of the Milford haven waterway. I used the Ef70-300 set at 225mm to get the compression I wanted in the image.

I have made this image to try to explain why image stacking is often necessary in astrophotography.
It shows two different exposures of the same area (around Alpha Delphini) cropped from the full frame.
You see the photos on the left, the upper one was 2.5 seconds exposure at ISO 3200 and the lower one was 40 seconds at the same sensitivity.
On the right are graphs of the brightness profile along the horizontal line through the brightest star (Alpha Del). I deliberately angled the photos so there are two fainter stars on the same line.
The graphs have 4 traces: one for each of the colour channels (RGB) and black would be the monochrome version (actually root sum of squares at each pixel).
The camera had 14 bits per channel, which means the (digitised) brightness in each colour at any pixel can only have values from 0 to 16383 (2 to the power 14 minus 1). So there is a limited range that can be represented and even for the short (2.5s) exposure the bright star is saturated: its peak would have gone above the maximum and so it is chopped off and set to 16383.
The lower part of every trace is for the background (sky) pixels and it is quite clear that even for the short exposure they are not zero. Furthermore the red trace is always higher than the green and blue ones, which is typical of pollution from street lamps.
On the longer exposure (lower photo) we can see that the background is really high, leaving little room between that and the maximum. Hence the reddish fogged photo and a smaller brightness range of stars can be discriminated.
So we have to keep individual exposures short enough to keep the background as near zero as possible and also to keep as many stars as possible from saturating.
When we do that though the level of the fainter stars is barely above that of the background and they tend to be lost in the fluctuations (noise) of the background.
Stacking helps (if the software does it right) by adding the pixels up in a memory area that allows a much greater range of brightness values before saturation.
When I started trying to do this, around 2001, there was nothing available that could cater for the large images from DSLR's, only for the much smaller images made by CCD cameras. So I started to write my own software, which I call GRIP (GR's Image Processor - I had worked in imaging software in the 1980's and 90's, which helped).
GRIP has an accumulator image in memory that has 32 bits per channel for every pixel, so brightnesses up to 2 to the power 32 can be represented before saturation would occur. (You would need to add more than 250000 14-bit exposures for any saturation to occur so, yes, it's overkill but convenient for programming.)
So if we accumulated 16 of the 2.5-second exposures the result would be similar to a 40-second exposure except that the profiles would not be chopped off at the top. The trick then is to read out the accumulator into a normal image through a look-up curve which takes the minimum of the background level down to true zero, stretches the contrast of the levels just above the background to make faint stars more visible, and takes the maximum actually occuring brightness (of the brightest star in the image, if none have saturated) to the maximum of the target image (which will have either 16 or 8 bits per channel).
NB: If intending to do photometry, to measure magnitudes of stars, the contrast must be kept linear. Also no stars involved in the measuring must have saturated.

These plastic stackable drawers cost about $7 for a set of three drawers. We screwed them into the base of the closet and into the back of the closet. They are solid as a rock - no tipping.
This is Oliver painstakingly stacking and unstacking his stacking toy, riht after he learned how to use it, at about 10 months.

I posed a question on the blog today, asking what you like to see in the "basics" chapters of quilt books. I'd love to know if you'd care to take the time to let me know! Blogged.
Focus stacked in Element 12 with plug-in.
using two images should have been 3 as mid ground is not sharp. Still its a economic way to get focus tacking in Photoshop Elements. using smart phone to control camera on low tripod. with out having to get on my knees I could adjust position of camera on tripod looking at phone screen.
